This invention relates generally to the art of draining surfaces of all types and more particularly to draining floors, such as the floors of shower baths and the like. It is a primary object of this invention to provide an improved floor drain for conducting water from a shower bath floor or the like to a drain pipe. It is also an object of this invention to provide a floor drain of simple form and construction which is adapted to accommodate a flashing sheet of lead or other waterproof material for conducting away seepage from the floor. It is a further object of this invention to provide a floor drain adapted to conduct seepage water which may accumulate on the flashing sheet through the floor drain and into the drain pipe.

It is a further object of this invention to provide a floor drain which can be easily assembled and which can be readily adjusted for difierent thicknesses of floor. In this connection it is an object of the invention to provide a floor drain in which the parts thereof above the flashing sheet may be assembled in a unit and subsequently bolted as a unit to the main portion of the assembly.

It is a still further object of this invention to provide a floor drain having a drain supporting member adapted to screw on to the upper end of a drain pipe and which is adapted to support said drain pipe during installation of the device and before the drain floor has been laid.

It is a particular object of this invention to provide a floor drain having an annular clamping plate of improved design having a threaded hole in its center into which is adapted to be threaded a nipple carrying at its upper end and threaded thereon a drain inlet member. It is a particular object of the invention to provide a clamping plate which will effectively drain the accumulated seepage on it into the drain pipe.

It is a still further object to provide a floor drain which will not become clogged by careless laying of a cement floor around it.

These objects are achieved by the structure set forth in the drawing in which:

Fig. 1 is a sectional elevation of the invention;

Fig. 2 is a plan on line 22 of Fig. 1, and

Fig. 3 is a sectional perspective View of the clamping plate of the invention.

Referring to the drawing it will be seen that the floor drain assembly has been shown as it would appear mounted in a floor. Reference numeral I I indicates a wood support for the concrete floor I 2 on which is laid a drain floor of tile I3. The floor drain itself comprises a basin member generally indicated at it and shown as resting upon the wood support or timbers I I. The member I4 is adapted to support the entire assembly upon suitable supporting members I I until the remainder of the floor portions I 2 and I3 has 5 been installed. The basin member I4 is shown as comprising an annular plate portion I5 and a downwardly extending hub It. In the center of the plate portion I5 and a portion of the hub I6 is a recess I? which terminates in shoulders 10 i8 adjacent a threaded opening I9 at the lower terminus of the hub member it. The basin member M also has an upwardly and outwardly extending peripheral flange 29 forming a shallow basin 2I. Internally threaded holes 22 are also 15 located in the member M. A drain pipe 23 screws into the threaded opening E9 in the body member. A flashing sheet 24 of lead or other waterproof material rests upon the basin 2I of the member l4 and extends up and over the flange 20 20. This sheet has an annular opening 25 adapted to register with the recess I] of the body member. Disposed on top of the flashing sheet 24 is a clamping plate 26 annular in shape which is internally threaded at 38. The clamping plate 25 has holes 21 into which are adapted to fit bolts 28 which screw into the threaded holes 22 of the body member M. The flashing sheet 24 is punched or otherwise provided with openings 33 to accommodate the bolts 28. The clamping 30 plate 26 also has downwardly and outwardly flared ports 29 adapted to drain any accumulation of seepage on top of the clamping plate member. These ports 29 are located above the recess I 'I and will, therefore, permit drainage 35 thereinto.

The clamping plate 25 when clamped into position on top of the flashing sheet 24 assumes the basin like form of the upper portion 2| of the member it, thus permitting seepage to accumulate on top of the plate 26 and drain through the ports 29.

A nipple 3| externally threaded at each end is adapted to thread into the internally threaded hole 30 in the clamping plate 26. However the threads in hole 30 terminate just short of the lower end of the opening in the hub portion 26'. This construction permits the nipple 3! to be threaded into the plate 26 but does not permit 50 it to be threaded through it and protrude beyond it. At the upper end of this nipple 3I any suitable drain inlet member 32 may be threaded thereon. The invention contemplates the use of different length nipples in order to provide an 55 adjustment means to adapt the floor drainto difierent thicknesses of floors.

From the above description it is apparent that the flared construction of the drainage ports 29 provides adequate drainage of accumulated seepage water. This construction in connection with the large recess I1, and the fact that the clamping plate is so threaded as to prevent the nipple being threaded through it and protruding into the recess I], prevents stoppage of the seepage drainage passages and the drain outlet itself by any possible influx of cement during the laying of the cement floor.

Furthermore, it will be seen that in assemblage of the device it is possible to assemble the upper portions as a unit, namely the inlet member 32, the nipple 3| and the clamping plate 26 and they may then be bolted down by the bolts 28 as a unit. This greatly facilitates installation of the device. This type of construction, embodying a clamping ring into which is threaded the nipple carrying the drain inlet member, provides a much more rigid and solid floor drain than is possible with other types of construction.

I claim as my invention:

In a floor drain: a flat basin member having an upwardly extending flange at its periphery and a central drain opening; means for supporting the basin member in the floor; a water impervious sheet on the basin member; and a drain unit consisting of a flat clamping plate on said sheet having a central drain opening therethrough; a

nipple threaded into said plate; a drain inlet member.
